OWC10 migrated to .Net empty images created..

[Bob [BVP]]

I have OWC10 Pie chart that works fine in classic asp, but
does not render the image in .aspx ? The app runs, no errors
but it generates an empty image file. Maybe you guys have
an idea ? I initially thought it must be permissions, then
I thought the datatype/data issue.. I have plucked around with
no sucess.. the data looks fine.. Just no image.. ?? Anything
obvious come to mind ?

oChart = New OWC10.ChartSpace
c = oChart.Constants
oChart.Border.Color = c.chColorNone
sCaption = "Managed Assets"
oChart.Charts.Add()
oChart.Charts(0).Type = oChart.Constants.chChartTypePie
oChart.Charts(0).SeriesCollection.Add()
oChart.Charts(0).SeriesCollection(0).Caption = sCaption
oChart.Charts(0).SeriesCollection(0).SetData(c.chDimCategories, c.chDataLiteral, PieCategories)
oChart.Charts(0).SeriesCollection(0).SetData(c.chDimValues, c.chDataLiteral, PieVals)
oChart.Charts(0).HasLegend = True
oChart.Charts(0).HasTitle = False
sFname = "reports\" & Session("FSO").GetTempName & Session.SessionID & ".gif"
' show a logo.gif just fine, so I know that the .binarywrite is working correctly..
' sFname = "reports\cpa_logo.gif"
oChart.ExportPicture(Server.MapPath(sFname), "gif", 610, 550)
' Response.BinaryWrite(oChart.GetPicture ("gif", 500, 400))
' ChartHolder.Controls.Add(new LiteralControl(sFname))

response.Write("<tr><td wdith=340><img src='" & sFname & "'></td></tr>")
response.Flush()

Thanks, Bob

Ok, installed the Office XP "Primary Interop Assembly" (PIA), registered the
assemblies.. modified my machine.config, and imported the correct
namespace.. but the first statement in the code below is
failing ? What am I doing wrong ? Clues appreciated..

re-register you owc10 dll at the command prompt
regsvr32 owc10.dll. after that, your call should succeed
